We found Calis to be VERY busy this year, and had to wait far too long in a few restaurants, which is unusual.
Our 18 year old daughter flew out to join us for a week, and she just loves the Roka. We've never had any problems and have eaten there many times (it's close to our apartment). As it was her first night, we went there - it wasn't particularly busy, though there was a largish party booked in later. Our meals were so slow, we all lost the urge to eat, having had a couple of beers, which killed our appetite. My daughter's pasta was barely enough to feed a young child, let alone an adult, and the starters were almost non-existent for six of us! We didn't complain, as we love the restaurant, and this really is very unusual in our opinion.
This happened to us in two or three other places during our holiday, always when we had family with us, and after we had praised up the restaurant beforehand!!!
